well known to the merchantsand public. Attempts have been made toeliminate and avoid 10 such moisture condensation, as by creating aforced circulation of air over the window with an electric fan, but thisractice is notalways convenient or feasible. he present invention aimsto provide a simple apparatus for removlg ing excesslve moisture fromthe an; and for creating a circulation of air as well as for cooling theair at the inner side of the window.

Broadly my invention resides in the removal of moisture from the air atthe inner 2 side of the show window, or other surfaces designed to befreed from having the moisture in the air condensed thereon. Thereferred embodiment of my invention resi es in arranging a coolingelement so that the air at the inside of the window will be caused tocome in contact therewith andwthe moisture in the air will condense uponthe cooling element and thereby render the air free from excessivemoisture.

While the-air may circulate through a system which embodies the coolingelement, a simple form of the invention is illustrated in theaccompanying drawin s in which thecooling element is disposed adj acentthe window,

- preferably in a-position concealed from an exterior view through" thewindow or so arranged as not to detract from the appearance of thewindow, for the purpose of cooling the air to a temperature more nearlyapproximating the outdoor temperature.

In its preferred embodiment the invention contemplates the arrangementof the cooling unit ad acent the top of the window and connected to arefrigerating mechanism arranged in a compartment or room separate fromthe show window, as in the basement of the store. Underl ing the coolingmember are arranged means or removing such waters of condensation as mayhave become deposited thereon in the form of an icy'coating and whichwill thaw during the periods of rest on the the coolin unit.

Inthe rawings,

Fig. 1 is 'a more or less diagrammatic view 111 perspective illustratingthe condensation preventmg apparatus installed at the inner side of ashow window.

Fig. 2 is a detailed cross sectional view depicting more clearly thecooling member and its associated trough.

Referring more in detail'to the accompanying drawings, the numeral 1designates the show windowof a store adjacent the inner part of side of.which is disposed the tubular or cylindrical cooling element 2 of theapparatus. This cooling element is depicted as being an portion of thewindow so t at as the alris cooled thereby such cooled air will tend tofall or descend across the inner face of the window 1 and tend to createa circulation in which the cooler air has initial contact with thewindow. The arrangement of this cooling element'adjacent the top of thewindow permits the same to be more readily concealed to view from theexterior of the window by the usual window drapes and trim-' mings.Since the cooling member 2 is colder than the inner face of the glass.of the window the moisture in the .store air. will condense upon saidcolder member and gradually form an icy coating therefor. In View of thefact that the modern show windows have their display space partitionedfrom the remainder of the store by paneled walls, the air within theshow window is more or less confined so that the action of thecooling'memberwill be to remove excess moisture from this confined airand render itcomparatively dry. Under this condition of the air thecoolin member ma be discontinued in its operation for a brie period, oruntil the air has been sufficiently mingled with moisture-ladened'air asto necessitate its functionmg in order to prevent the moisture fromcondensing upon the glass. When the cooling member is inoperativethei'cy deposit thereelongated body arranged ad'acent the upper vdensation will drain as through pipe 4 to a suitable escape.

The cooling member 2 is connected by pipes 5 and 6 in circuit with anexpansion tank 7 forming part of a refrigerating apparatus embodying acompressor 8 and its operating motor 9. The major portion of theapparatus, including the motor, compressor and expansion tank, ispreferably dis osed. in a concealed position, such as in the asement ofthe store, as diagrammatically illustrated in Figure 1.

The apparatus-thus described will effectively prevent the condensationof water vapors upon the interior of the window by cooling the airadjacent the inner face of the window to a temperature approaching oreven colder than the outdoor temperature. In

.addition to this a considerable portion of 1. Condensation preventingapparatus for show windows, comprising in combination means forrendering the cooling element operative for the condensation andprecipitation of water vapors of the air ad acent thereto, and a troughunderlying the element trough.

6. The method of preventing condensation on show windows, or the like,cofgsisting in cooling the air ad] acent the top o a window therebycausing a downfiowing current of air to pass over the window andsimultaneously condensing and precipitating the vapors in the air. I

7. In combination with a show window, a cooling member 'of arefrigerating apparatus mounted adjacent thereto, for creating acirculation of the air at the inner side of the .window andsimultaneously acting to remove excessive moisture from the air wherebythe air is rendered partiljjv dry. v RWIN C. HORTON.
